Chuck Simon's fall2012 Opus
Chuck's Fortress of Solitude
Introduction
Hey guys, I'm a dude. So yeah, I was asked to do this opus thing and that's what I'm doing. About me: as I said before, I'm a dude. I may seem quiet and distant, but it's only because I don't know anybody yet.
Anyway, a list off of some interests of mine:
*Computers: Why I'm taking this class in the first place. I need to know as much as possible if I want to make it big in my desired future.
*Video Games: Every variety. I often try to find out about games people don't usually play, which is why I'm not very knowledgeable about the new best things. However, if someone has a question about an offbeat game of some variety, I will be happy to give some info (i.e. Cho Aniki).
*Character Design: I love to design monsters and characters for games and stories and such (and yes there are three ands in that sentence and).
Anyway, enough for now. I did this intro at the last minute, so I won't say much. I'll update later.
Part 1
Entries
Entry 1: September 28, 2012
While doing the puzzlebox project I came up with the question, is there a type of file that the command file can't recognize?
Entry 2: August Day, 2012
Today was also the day that the class realized that, it was in fact the last Friday of September that we had class. I believe that everyone in the class had their minds blown at this fact, and I believe I may have died a little inside. I will never get to experience another September Friday in this class again.
Entry 3: September 30, 2012
I'm not going to lie, this post is only a post to be a post. I'm probably not going to get graded positively for this post, but oh well. Instead, I will put an ASCII art of Mickey mouse from Chris.com.

Entry 4: September, 30, 2012
Today was a wake up call for me. I realized how stupid I was for not doing my Opus entries earlier and I need to get my act together and start doing them in a timely manner from now on.

unix Keyword 1 Phase 2
Identification of chosen keyword: Current working directory
Definition
Definition (in your own words) of the chosen keyword:
THE WORD(S) OF THE DAY IS(ARE): CURRENT WORKING DIRECTORY. *Note: If you haven't read Unix for the Beginning Mage yet, some of the terminology might seem odd.
COMMENCE
The current working directory refers to the absolute path of where you are “standing”. To find out where, exactly, you are standing, type “pwd” into the terminal. You should get an output; if you don't, I'm sorry. This output will change as you change your position in the file system. The prompt will also change as you move around. To illustrate a few concepts, I have made a directory in my home directory called “cwd” (current working directory) and a few directories therein.
lab46:~$ mkdir cwd lab46:~$ cd cwd lab46:~/cwd$ mkdir file lab46:~/cwd$ cd file lab46:~/cwd/file$ mkdir music lab46:~/cwd/file$ cd music lab46:~/cwd/file/music$ pwd /home/dsherbur/cwd/file/music
In the prompt, lab46 refers to the system's name (as far as this entry is concerned). Then there is a colon (:), and, if you are standing in or past your home, there is a tilde (~). The prompt can help you identify your current working directory without having to type pwd. The tilde refers to the path of your home directory, which is usually /home/username. Everything after the tilde and between the dollar sign is your current directory. If you are not in the home directory, or you are in a directory contained within the home directory, the prompt will not have a tilde in it.
lab46:~$ cd / lab46:/$ pwd /
I changed directories from my home directory to the root directory. The prompt no longer uses a tilde because root is not part of home, but rather home is a part of root.

Demonstration of the indicated keyword.
If you wish to aid your definition with a code sample, you can do so by using a wiki code block, an example follows:
/* * Sample code block */ #include <stdio.h> int main() { return(0); }
Alternatively (or additionally), if you want to demonstrate something on the command-line, you can do so as follows:
lab46:~$ cd src lab46:~/src$ gcc -o hello hello.c lab46:~/src$ ./hello Hello, World! lab46:~/src$
Experiment 1
Question
What is the question you'd like to pose for experimentation? State it here.
Resources
Collect information and resources (such as URLs of web resources), and comment on knowledge obtained that you think will provide useful background information to aid in performing the experiment.
Hypothesis
Based on what you've read with respect to your original posed question, what do you think will be the result of your experiment (ie an educated guess based on the facts known). This is done before actually performing the experiment.
State your rationale.
Experiment
How are you going to test your hypothesis? What is the structure of your experiment?
Data
Perform your experiment, and collect/document the results here.
Analysis
Based on the data collected:
- Was your hypothesis correct?
- Was your hypothesis not applicable?
- Is there more going on than you originally thought? (shortcomings in hypothesis)
- What shortcomings might there be in your experiment?
- What shortcomings might there be in your data?
Conclusions
What can you ascertain based on the experiment performed and data collected? Document your findings here; make a statement as to any discoveries you've made.
Part 2
Entries
Entry 1: October 5, 2012
I came up with the question after doing project 2; Is it possible to create a file that can not be opened with the keys we learned (“”,\,*)?
Entry 2: October 30 2342
I come from the future to notice that there are two separate experiments showing up on my opus page. Does that mean that I had an experiment due and didn't realize it? Must ask Matt when I go back in time again to visit his class.
Entry 3: October 30 2012
Realized I completely destroyed my last entry and can't recover it (with my current knowledge). Must Ask Matt what might have caused it when I go to class.
Entry 4: The freaking last day of October, 2012
A major question came up: how in the depths of Hades do you seperate single phrases (I can't think of how to word it) out of sed regular expression, from the part you're deleting. I know about [^ ] but I have no idea to make it work. Also, is it possible to take a single sed expression and do ANYTHING without making a new sed expression? The world may never know.
